WEBB, OF LOS ANGELES, CALIFORNIA, ASSIGNORS TO CHARLES R. HADLEY COMPANY, OF L OF CALIFORNIA i OS ANGELES, CALIFORNIA, CORPORATION TRAY kBINDER Application :filed Februaiy 13, 1928. Serial No. 254,020.

This invention relates to tray binders.

One of the principal objects of this invention is to make provision for holding sheets of diHerent widths. Tray binders have been heretofore made with adjustable guide rods that may be moved into different positions, one position close to the edge of the binder end member when the leaves are not offset and another position removed from the ends of the binder end members so as to permit offsetting of the leaves. Such prior tray binders, accordingly, could not take leaves of any materially greater width than those for which the tray binders were voriginally designed. This invention makes it possible to adjust the tray binder to radically different widths of sheets so that tray binders of one size can be manufactured and carried in stock to meet the demands of a much larger clientele than was possible with the prior tray binders.

Other important objects of the invention are simplicity and inexpensivenessgof construction.

Another object is neatness of appearance.

Another object is to provide a construction which is largely punch press work.

Another ,object is to make it impossible to release the binder leaves without using a properly constructed key wherewith to turn the feed screw.

Other objects and advantages will appear in the subjoined detailed description.

The accompanying drawings illustrate the invention:

Figure lv is a perspective view of a tray tical section on the line indicated by 6 6,

Fig. 5.

Figure 7 is an enlarged sectional detail of the construction at the right end of Fig. 5.

Figure 8 is an enlarged sectional detail of the construction at the leftend ofk F ig. 5.

Referring to the drawings, there is provided a flat support V11 on which the'lower sheet-metal of which the support 11 is constructed.v Along its median line, the support V11 is provided witha channel 12. ln this instance,`the support 11 comprisesa main section 13 and a central U-shaped section 14, the opposite sides of vwhich are secured to down-turned 'flanges 15 of the section 13. The section 13, betweenthe flanges 15, is provided with a longitudinally extendingk slot 16 which opens into the U-shaped section 14. The sectionsl, 14 are prefer ably made of sheet-metal. The slot 16 is somewhat shorter than the section 13 and the end portions of -the section 1S are bent downwardly at 17, thence inwardly A.it-1S to form transversely extending guides in which are slidably received downwardly projecting flanges 19 of side .extension meni- Ybers 20 of the support 1l. The extension members 2O each comprises a flat portion 21, that slides beneath the section 13, and an upstanding flange 22..:The extension niembers k2O are also preferably of sheetmetal.

Inv Figure 3 the extension'members Q0 are shown in their innermost positions inV solid lines, thus giving vminimum width between the .flanges 22 for receptioii'of the binder leaves A, and one of the extension members 20 are indicated in broken lines in position to widen the support 11 for the reception of leaves of a greater width.

along its lower edge with notches 23 which are adapted to be selectively engaged by a detent 24 mounted on the guide 17 In this instance, the detents 24, of which there are four, are detachably connected with the guides 17 by threaded members in the Jform of screws 25 which are screwed into the detents 24 that are in the form of nuts. In this instance, the heads 26 of the screws 25 constitute the feet of the tray binder and arev preferably made of rubber. To adjust the members 2O to diierent positions the screws 25 will be unscrewed from the nuts 24 and then the members 2O will be shifted into the desired position. The nuts 24 will then be placed in engagement withthe notches 23 that are positioned adjacent to the screws 25 and said screws will be screwed into the nuts to hold them in place.

The guides 1'? are `provided in line with the channel 12 with bearings 27 in which are mounted the kopposite ends of a feed screw 28, a portion ot' said screw being provided with right-hand threads and another portion with left-hand threads. The threaded portions of the screw 28 are screwed through feed blocks 29 which are secured to clamping members 30. The feed blocks 29 are approximately of the same width as the channel 12 between theiianges 15 so asto be guided by the walls of said channel. This eliminates the use ot the pair of rods disclosed in Canadianpatent No. 264,657, issued to Charles R. Hadley and issued September 28, 1926.

One of the guides 17 is provided in alignment with the screw 28 with an oriiice 31 into which can be inserted a key 32 ccnstructed in the form of a crank, the key being provided with slots 33 to engage a pair of laterally projecting shoulders 34 on the screw 28. The shoulders 34 lie within the orifice 31 and, accordingly, the screw 28 can not be turned excepting by inserting the key 32 in said orice.

Hinged at 34 to the clamping members 3() are end members which serve to hold the leaves A in vertical position or to hold said leaves aslant, in a manner well understood in this art, so thatthe entries on said leaves can be read oif. An adjustable means, indicated at 36, is provided for adjustably positioning each or' the end members' These adjustable means will not be described in detail herein, since they have been fully disclosed in the prior patent mentioned above. f

To use the invention, if it be desired to remove or replace any7 of the leaves A, the key 32 will be applied tothe screw 28 and turned in the appropriate direction to etect movement of the blocks 29 away from one another, thus unclamping the leaves between the clamping members. If 1t be de sired to place in the tray binder leaves of `'formed of sheet-metal sections, one oit the greater width than the width of the section 13, the extension members 20 will be releaseds and slid outwardly to the required positions and then locked in those positions, as hereinbefore described. It is to be understood that this may be done, even though the leaves project beyond the side edge or edges of the end members 35. However, if desired, end members and clamping members of a width to correspond with the width of theleaves A may be substituted for the narrower ones and it is preferable to do this if the extension members 19 are opened out to any very great extent, in order to properly protect the leaves when the end members 35 are in closed position.

A guide-locking rod 37, of a character well understood in thls art, may be provided to extend lengthwise in the channel 12. One end of the rod 37 passes through a hole 38 in one of the guides 17 and the other end of said rod 37 is threaded into a nut 39 secured in any suitable manner to the inner surface of the other guide 17. The rod 37 passes through holes 40 in the blocks 29.

To insure against upward springing oi the middle portion of the screw 28, that may result Jfrom tightly clamping the lower margins of the leaves A, we preferably provide a half-bearing 41 enga-ging the upper half of thefsmooth portion 42 of the screw 28. rlhe half-bearing is welded or otherwise secured to the flanges 15.
